dismax and multi-language corpus
Hello list,
I have a corpus with 3 languages, so i setup a text content field (with
no stemming) and 3 text-[en|it|de] fields with specific snowball stemmers.
i copyField the text to my language-away fields. So, I setup this dismax
searchHandler:
<requestHandler name="content" class="solr.SearchHandler" default="true">
<lst name="defaults">
<str name="defType">dismax</str>
<str name="pf">title^1.2 content-en^0.8 content-it^0.8
content-de^0.8</str>
<str name="bf">title^1.2 content-en^0.8 content-it^0.8
content-de^0.8</str>
<str name="qf">title^1.2 content-en^0.8 content-it^0.8
content-de^0.8</str>
<float name="tie">0.1</float>
</lst>
</requestHandler>
but i get this error:
HTTP Status 400 - org.apache.lucene.queryParser.ParseException: Expected
',' at position 7 in 'content-en'
type Status report
message org.apache.lucene.queryParser.ParseException: Expected ',' at
position 7 in 'content-en'
description The request sent by the client was syntactically incorrect
(org.apache.lucene.queryParser.ParseException: Expected ',' at position
7 in 'content-en').
Any idea?
TIA
Claudio

Claudio,
Ah, through multilingual indexing/search work (with http://www.sematext.com/products/multilingual-indexer/index.html ) I learned that cross-language search often doesn't really make sense, unless the search involves "universal terms" (e.g. Fiat, BMW, Mercedes, Olivetti, Tomi de Paola, Alberto Tomba...). If the search involved natural language-specific terms, then searching in the "foreign" language doesn't work so well and doesn't make a ton. Imagine a search for "ciao ragazzi". I have no idea what the Italian stemmer does with that, but say it turns it into "cia raga" (it doesn't, but just imagine). If this was done with Italian docs at index time, you will find the matching docs. But what happens if "ciao ragazzi" was analyzed by some German analyzer? Different tokens will be created and indexed, so a "ciao ragazzi" search won't work. And this Analyzer would you use to analyze that query anyway? Italian or German?

Re: dismax and multi-language corpus
Posted by Claudio Martella <cl...@tis.bz.it>.
I'll try removing the '-'. I do need now to search it. the other option
would be to request the user what language to query. but in my region we
use italian and german in the same quantity, so it would turn out in
querying both the languages all the time. or you meant a more performant
solution of query both the languages all the time? :)

I agree. I just didn't have the chance to look at it closely to get enough details for filing in JIRA.

I don't know, but the other day I did see a NPE related to fields with '-'. In Distributed Search context at least, fields with '-' were causing a NPE.
